' parentl later on, however, :features ot the involition are capable of use in machines for othersgnicitic purposes and, While the terins cancoiler and sliverware repeatedly used herein. this is Alor invenience only, and the use olf those terins is not to be considered as limiting the inventions either to such `niaor to lthe handlingl of such materials. trouble experienced With all prior nia ot the kind, so tar as the applicants are aware, has been that changes in humidity or temperature, and the development of static conditions have interifered Wit-h the correct fnnc'tioningv or' the machines. `Such prior machines have also been unable to coil unitorinly and satisfactorily, even under avorable conditions, light or fine slivers as Weil as they did the coarser ones. One ot the ohjectsot this invention is to `provide a inaclnne which is capable ot handling a complete range oiI sliver-s, including the very l'ne oneIV` Without interference or rntcrruption because ci? the degree of ineness or because of runtavorable atmospheric or static conditions.

Another object olf `the invention is to provide atop inotiondevices vcontrolled by the sliver n' halting),` operations ot' the machine when certain conditions arise. llihile Jthis mechanism niay, 'tor example, be so con- `etruc'ed as to he called into play by either the accinnnlation of the sliver 'in the cans or liv break or other interruption rin the supply oiE sliver, the use ot both is preferred nrw nit embodiment, thereby prever. in; the' hi e -freni pacl'cing the sliver in the cane so t" y that there is difficulty later insatisfactorily nncoiling Ait and at .Janie time proi'iding a means for yattractl the attendant if a nia# L .l because the can is filled a brealior lack of material to work upon.

While in the accompanying drawings the improvement-s are shown in the torni they l take when applied to or lused in connection with a carding machine, it is obvious that the various parte niay he Inodiiied and rearranged to cooperate with other machines or sources of supply ol material.

lilith the foregoing and incidental objects in view, the invention consists in a novel constrncti on and arrangement ot parts, the

novel treatin-es ol which are pointed out in the claims and a preferred embodiment ot whichis shown in the drawings accompanyingV and itforniingl a part ot this specification.

Fig. 4 isa view partly in section, on the line H of Fig. 2;

Fig. 5 is a section through the base oi the machine, on the line 5-5 of Fig. 3;

Fig; 6 is a detail olf the sliver feeding rolls .and the parts immediately associa-tedy y therewith cai-ding machine and brought into what niay, tor convenience, be termed a loose strand which is, at the beginning oit the operation oi the machine, passed through suit able guides and into engagement with a pair of feeding rollers. These rollers are so inountedfthat they ydeliver thel sliver to the interim-@ot the can through ,anopening or passage `which does not niove `relatively to the rolls and whichA is soshort that there is substantially,noresistance to the passage of` the sliver thro ugh it. In prior devices Lil (ill

known to the applicants the feeding rollers are so mounted that a long guide necessar f to conduct the material trom the rolls into the can and this guide has a movement relative to the feeding rolls. Such a long guide, coupled With its relative movement, makes it necessary for the rolls to push the sliver through the guide. i It is oln'iousthat this is unsatisfactory for handling line slir ers, for example, ot silk, and that the inovcment of even fairly `coarse ,material may easilyA be interfered `with by the derelopn'ient of'a static condition or by untavorahledegrces of temperature or humidity.

The preferred embodiment also comprises two stop motion connections. Gne of these is so'` arranged that when a can or corresponding receptacle is packed to its intended capacity the packed material acting against a movable head Willli'tt a lug or other projection into a position where it will engage and actuate a stop n'iotion elementj The other stop motion connections comprise a member which is, in the preferred form, heldin an inel'l'lective position so long as material is coming through the'inechanism, W hen there is a break or the supply ot ma terial isinterrupted, the member relferred to is auto1naticall3`vv moved to a position Where it will he eit'ective to engage a stop motion element which may, asin the present construction, be the same oneas is actuated when the can has' been packed toits capacity.

Describing the construction in detail, and with reference to the accompanying dra'W` ings,` the carding machine maiv have an ex` tension such as indicated indotted 'lines at l0, Fig. l. The upper part o t the coiling mechanism may be .supported by a trame lll secured to the extension lllo'i' the carding machine. The earding machine comprises` a delivery roll 11, driven in acloelrwise direction, Fig. l, by any suitable belt or gear drive. Rigid iviththe `deliver)y roll 'l1 is an internal gear l2, meshing with-r pinion: 13, Fig. i2. Rigid with the-pinion '1,3 is a' pinion 14 meshing with a pinion l5 vwhich in turn meshes with a pinion or `gear 1G secured to a shortshatt 1"( journaled in a boss or extension iSo'f thet'raine lll.

ribs corresponding with grooves in a stationary hase 32 in such wat1 that the rotary base can turn on its axis $323 and at the saine time he suitably supported against any tend encjy7 to roch or tilt.

150th the gearing ior driving the ring gear Q-.l and the head moving thereui'ith, and the gearing for driving the rotary c: n hase 3l, are ot the change-speed type, that is, gears haring clitierent gear ratios may roadilji` he substituted, and eorresl'iouding relative adjustments made of the studs formii'ig the hearings for the gears.

The rotary can base fll. hasits` upper suriace suitably torined to receive the usual can or receptacle 1:55 in such way that rotation ot' the hase will cause a correspoiidinu* rotation ot the can.

rthe ring gear 2l is, as liest shown in Fig. el, loosely mounted in a circular hear ing 36in a plate 3? (see also Fig. 2) forni ing a part ol" the machine framing. lntegral with the ring gear EM; are lu ll 1which toi-1n a convenient: means by which a polii-zhed metal plate 31) may be recnrezfl to and caused to turn with the gear. This plate and its supporting connections form what hereinafter referred to as the movahlc head i'or the can.

ltigid with the main 'frame lll is a plate ll; slotted as at 4t2. Fig. il, to serve as a guide tor the web ot libere coming :lroln the delivery roll 11. From the slot il@ the libere:`

Losanna to the plate The short guide is, in some respects, preferable to simply an opening,

as its top can be formed so as to contorni somewhat to the configuration of the feeding rollers and thereby prevent the iibers trom remaining in engagement with and bcing woundaround the rolls.

From the foregoingit will be seen that the construction is such that the feeding rollers are mounted in close juxtaposition to the opening in the rotary head, and that, in fact, the material .is practically delivered to the interior ot the can `without having to be pushed or forced through a chute or guide of substantial length. It will also be seen that there no movement of the opening or guide 6l relative to the feeding rolls 47 and 48. The advantages of these teatures have already been pointed out in a general way.

The stop motion devices hereiubet'ore re- .lierredto may comprise any suitable electric or belt shifting mechanism, but in the present instance the showing is amore or less conventional one, of mechanism of the belt shitting type. A shaft, which may be movable endwise to operate a shifting fork, is shown at 57, F ig. l. This shaitt, as is usual in such constructions, may be latched in one position by a weighted bell crank 58 and moved to the other position by a counterbalance or spring, not shown, when the bell crank is lifted out of engagement with a collar 59 or other suitable projection on the shat't 57. This bell crank 1s connected by the usual wire or rod Gl to an arm G2 rigid with the trumpet 44C. It is apparent that it the trumpetlel is turned counterclockwise (Fig. l) on its pivot l, the bell crank 58 will be lifted to release the stop motion mechanism. i

The trumpet elet is lifted or rocked. as gust mentioned, either when the can has neconie packed to its capacity or when the .sliver or strand of material has been broken or the supply of material exhausted. For

the purpose oi operating the stop motion4 mechanism when the lirst contingency arises, the rotary head, comprising the ring gear Q-iland the polished metal plate 39, has oneor more lugs such as shown at 63.

Vlfllhen the can has been filled to its capacity the movable head will be lifted by the material, thereby raising the lug 63 until it will strike a suitably termed portion 64- on the trumpet del and rock the trumpet' Llar enough to act through the connection 6l to free the stop motion mechanism.

`ln order to actuate the stop motion when the other contingency arises, that is, when the sliver breaks or the supply of material `becomes exhausted. the ring gear 24 is provided with a shoulder or boss 65 (Figs. 2 and 7 to which is pivoted. at 66,r a pawl 67. The pawl 67 is so mounted that it has a .plate Si).

tendency to move by gravity in one direction, and this tendency is increased by ka portion 68 which serves as an additional weight at one side ot the pivotal support 'for the pawl. The normal position ot' the pawlis shown in Fig. 7, in which position it will clear the shoulder or extension 64 on the trumpet stel. This is what is, at cerf tain points herein, referred to as the inet iective position of the pawl.

ln this ineffective position one edge of the pawl is in Contact with a pin 7l projecting` horizontally from the head 72 of a bolt S73, supported 'tor longitudinal movement in the lugl (l5. Surrounding the bolt 73 is i a light spring 7 which in the normal posi tion of the parts. that is, while the sliver is running through the machine, is slightly compressed between the lugl G5 and a pin` 75 extending laterally from the bolt The head 7 2 ot' the bolt is slotted, as indicated at 7G (Fig. 2), to cooperate witha pin 77 extending upward `trom the ring gear rotation.

.As before stated. the guide or truniipet 4G is rotatable about a vertical axis. Rigid with the guide is an arm'Sl suitably slotted to engage a pin extending upward from the bolt 7". When the sliver is running through the machine it will hold the guide elG in the position in which it is shown in Fig. but it the sliver is broken or the supply of material forming it is exhausted, the

yguide will be treed and will then be swung to the position indicated by the dotted lilies 82, by the spring 74 surrounding the bolt 72, This will cause the pin 7l (Fig. 7) to rock the `pawl G7 on its pivot and bringthe edge 83 thereot` into or past a vertical posi` tion. in which position the upper tip of the pawl will be raised high enough to engage the shoulder Gat of the trumpet 44k and rock the trumpet in such a way as to actuate the stop motion connection (5l to arrest the movement ot' the mechanism.

In Fig. 2 the position of the can 35 is represented by dotted outlines, from which it'will be seen that the axes oit rotation ot the can and ol' the ring gear 2i are not in alignment. In other words, one is oil center with respect to the other. This causes the sliver to be coiled.v as indicated more or less diagrannnatically at 8st, Fig. 3. This coiling continues until the can is full, when the coil ot material will come in contact with `the underside ot the polished metal The plate will thereafter serve to pack the coiled material down in the can, doing this uniiornily and without disar rangement of the sliver. The packing con tinues until. the coiled material is packed closely enough to begin to lift the plate 39, and of course the ring` gear 24 and the parts supported thereby. This will disengage the it, thereby holding the bolt against` lllll and Will, as before described, bring;I the lug (S3 up to it position Where it will engage the shoulder lfl on the trunipet lil und operate the .stop motion connections.
